英文摘要PURPOSE:To enable the high output operation to be performed in low threshold value current by a method wherein a luminescence active layer is structured of multiquantum well layer laminated of a quantum well layer and a quantum barrier layer or a single quantum well vertically provided with photowaveguide layers. CONSTITUTION:An n-GaAs buffer layer 2, an AlGaInP photo waveguide layer 3, a multiquantum well active layer 4 laminated of a GaIn quantum layer and an undoped quantum barrier layer, an AlGaInP photo waveguide layer 5 and a buffer layer 6 are successively grown on an n-GaAs substrate 1 tilted from a face (001) by exceeding 10 deg. in the orientations [110], (-1-10) direction. In such a constitution, the title semiconductor laser element can be polarized in high TE mode while the TE upsilon intensity is much higher than the TE mode intensity. Through these procedures, the TE mode can be gained selectively to facilitate the laser oscillation thereby enabling the threshold current to be lowered.
